feat(machine): redesign cash-out with split-screen layout

Split-screen for displayingInvoice (info left, QR right), full-width
for selectingAmount. Add StepIndicator with warning flow accent header.
Replace Skeleton with BounceDots, remove ScrollArea and Card wrappers,
wrap states in Transition for fade animations.
